Windows & AD Security is Overwhelming.
Let's Fix That.
IT & security professionals are constantly expected to:
- 𝗦𝗼𝗿𝘁 𝘁𝗵𝗿𝗼𝘂𝗴𝗵 𝗲𝗻𝗱𝗹𝗲𝘀𝘀 𝗿𝗲𝘀𝗼𝘂𝗿𝗰𝗲𝘀 — but finding the right ones takes time you don’t have.
- 𝗝𝘂𝗴𝗴𝗹𝗲 𝗺𝘂𝗹𝘁𝗶𝗽𝗹𝗲 𝗿𝗲𝘀𝗽𝗼𝗻𝘀𝗶𝗯𝗶𝗹𝗶𝘁𝗶𝗲𝘀 — your company expects you to handle it all.
- 𝗞𝗲𝗲𝗽 𝘂𝗽 𝘄𝗶𝘁𝗵 𝗲𝘃𝗼𝗹𝘃𝗶𝗻𝗴 𝘁𝗵𝗿𝗲𝗮𝘁𝘀 — but attackers move faster than ever.
- 𝗠𝗮𝘀𝘁𝗲𝗿 𝗲𝘃𝗲𝗿𝘆𝘁𝗵𝗶𝗻𝗴 — but where do you even start?
💡 That’s why I created Horizon Secured.

As an aspiring Security Engineer, I highly recommend the Infrastructure Security course by Horizon Secured ,especially for anyone on the Blue Team side looking to strengthen their foundational knowledge.
While the course doesn’t include hands-on labs, the video lessons and demos are extremely practical and well-explained. The instructor does a great job walking through real-world attack and defense techniques.
What I found most valuable is how the course explains the “why” behind the techniques. Even without labs, the demos make it easy to understand how these attacks work and how to defend against them ,which is essential for anyone looking to move into Security Engineering or Defensive roles.
